Attack on Pearl Harbor

The Attack on Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service against the United States naval base at Pearl Harbor, Hawaii, on December 7, 1941. This devastating pre-emptive attack, launched while the US was officially neutral in World War II, aimed to cripple the US Pacific Fleet and prevent its interference with Japan's planned military actions in Southeast Asia. The attack killed over 2,400 Americans and directly led to the United States' entry into World War II.
